Example:
In a vessel 20 m high, the installation position of the sensor is 1.4 m
from the vessel centre.
The necessary angle of inclination of 4° can be read out from this
table.
Proceed as follows to adjust the angle of inclination with the swivelling
holder:
1. Loosen the terminal screws of the swivel holder by one turn. Use
ahexagonsocketwrench,size5.

2. Align the sensor, check angle of inclination
Information:
The max. angle of inclination of the swivelling holder is approx. 10°
3. Re-tighten the terminal screws, max. torque see chapter "Techni-
cal data".
The mounting location of the radar sensor should be a place where no
otherequipmentorxturescrossthepathoftheradarsignals.
Vessel installations, such as e.g. ladders, limit switches, heating spi-
rals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring point that the radar sensor
has a "clear view" to the measured product.
In case of existing vessel installations, a false signal suppression
should be carried out during setup.
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
